Nigel,
OK, it's easy to call. Why "hold" the call until the end of the period? If it is an escape, call it when it happens so both wrestlers know the situation. I simply think holding the call until the end of the period is unfair to the wrestlers. I think it would be easier for the refs to call it as soon as possible. I've never seen any call get the coach and fans upset as much as a call at the end of the match when it appears nothing has changed. I was not at the Bobcat, I'm not talking about a call at that tournament, I'm just trying to figure out why the call cannot be made when the ref decides it's an escape.
